Key level, squaring, and spacing: three areas that few pianists notice unless they are very poorly regulated. But all three areas dramatically affect the feel and function of the keyboard.
Adding to the fun on this keyboard were a few loose keytops that had not been glued well when they were replaced.
Taking care of your piano keyboard is one of the most visible and important cosmetic aspects of the instrument, but it also will make it much more enjoyable to play!
